Abstract: TITLE:    CONTINUOUS STRIP CASTING OF ALUMINUM ALLOY           FROM SCRAP ALUMINUM FOR CONTAINER COMPONENTS                    Abstract of the Disclosure A composition and method whereby aluminum scrap, including consumer scrap, is recycled into aluminum sheet and aluminum containers.  Aluminum scrap is melted in a heated furnace to form a melt composition.  The melt is adjusted to form the present composition, consisting essen-tially of silicon, 0.1 - 1.0%; iron 0.1 - 0.9%; manganese 0.4 - 1.0%; magnesium 1.3 - 2.5%; copper .05 - 0.4%; and titanium, 0 - 0.2%, the balance being essentially aluminum.          Aluminum scrap comprising consumer scrap, plant scrap, and can making scrap is heated to form the melt composition, which requires a minimum amount of adjustment to arrive at the present alloy composition.  The composition is then cast and fabricated into sheet having strength and formability properties making it suitable for container manufacture.          Container manufacture according to the process and compo-sition of the present invention comprises drawn-and-ironed can body manufacture and easy-opening end manufacture.          Sheet fabrication according to the present invention comprises continuously casting the molten composition to produce a moving strip; hot rolling the moving strip at casting speed; coiling and allowing the hot rolled stip to cool; and cold rolling the hot rolled stip to final gauge.

Granted: 1982-01-26
Abstract: ABSTRACT OF THE DISCLOSURE      A drive for a self-propelled lawn mower is provided. A transmission is mounted on a deck of the lawn mower and has a drive shaft extending toward each of two wheels rotatably mounted on opposite sides of the deck.  A driven gear is located adjacent each of the wheels and mounted for rotation therewith. Connecting means for connecting the drive shaft and each of the driven gears includes a pinion gear rotatably mounted on the drive shaft with an end of the gear having two diametrically-opposite shoulders.  A drive pin extends transversely through the drive shaft adjacent the shoulders and a spring is located on the shaft urging the pinion gear toward the drive pin.  When the drive shaft is driving the mower forwardly through the gears, the drive pin engages the shoulders of the pinion gear to pro-vide a driving connection.  When the pinion gear is rotating faster than the drive shaft, the drive pin rides up slanted surfaces adjacent the shoulders to accommodate the difference in rotational speeds.

Title: Propulsion device for tennis balls and like spherical  objects

Abstract: PROPULSION DEVICE FOR TENNIS BALLS              AND LIKE SPHERICAL OBJECTS                       ABSTRACT        A propulsion device is provided, designed especially for discharging tennis balls for practice purposes, at selected angles of inclination, and at a predetermined, selected velocity.     Employed in the device is a distributor, which is disposed between a hopper and an air pressurizing drum, the distributor being designed to feed balls, one at a time, to the drum, at predetermined intervals.     Within the drum, the ball is directed into a receiving tube, being impelled forwardly therein responsive to the build-up of air pressure within the drum.  Each ball is temporarily arrested by a radially expandable detent, until the pressure in back of the ball builds up to a predetermined value.  The ball is thus caused to be freed from the detent, and propelled forcibly out of a barrel disposed at an adjusted angle of inclination.     The distributor is disposed between the hopper and drum in such fashion as to cause the spherical objects to be efficiently agitated within the hopper, by passage over the exteriorly cylindrical surface of the drum while moving to the point at which the objects feed into the drum.  Efficient agitation of the spherical objects within the hopper thus assures to the maximum extent that the distributor will be fully charged with said objects.      A trap door, normally closed by air pressure within the drum, is moved with maximum speed to an open position responsive to the free fall of a spherical object from the distributor into the drum, and moves with equal speed back to a closed position.  By holding the open time of the trap door to a minimum, it becomes possible for the device to be interiorly constructed with a simple receiving pipe characterized by an absence of annular induced air flow assemblies and other arrangements which have heretofore been employed.

Abstract: METHOD AND APPARATUS FOR SEPARATING SOLID         PHASE FROM DRILLING MUD                               ABSTRACT     A method for separating solid phase from drilling mud, comprising forming from drilling mud an adhesive layer on a rotary closed curvilinear surface partly placed in the drilling mud, with subsequent feeding of an ionized gas jet along a tangent line to the adhesive layer, the gas jet entraining and removing solid phase particles from the drilling mud. The linear velocity of the adhesive layer in the zone of its contact with the gas jet is controlled by changing the velocity of the gas jet.  An apparatus for carrying out the method comprises a tank filled with drilling mud and accommodating a drum installed for rotation for forming an adhesive layer of drilling mud on its cylindrical surface during rotation of the drum, a nozzle which is arranged in parallel to a tangent line to the drum surface and communicates with a source of a gas under pressure for forming a jet of gas that entrains and removes solid phase particles from the drilling mud, and a pair of electrodes connected to a high-voltage d-c supply source for ionizing the gas jet.       The method and apparatus according to the invention enable the cleaning of all drilling mud by using comparativ-ly simple techniques.

Abstract: A B S T R A C T             DATA PROCESSING SYSTEM INCLUDING INTERNAL      REGISTER ADDRESSING ARRANGEMENTS          In a multi-processor system of the type in which each processor is provided with its own unique bus which has an addressing system organised in such a manner that all store locations and peripheral equipments are addressed as part of a comprehensive single addressing system.  Each address comprises a module number and an offset address.  Each module in the system includes a module number comparator which detects the presence of its module address on a CPU bus and allows the offset address to be active within that module.  The invention provides for the incorporation of similar mechanisms within a CPU allowing the CPU to address its own internal registers in an identical manner to its normal bus addressing mode.  In addition the offset address includes a "bit portion address" which selects a mask which is used when performing the required internal register operation.  The main advantage of such an arrangement is the simplification of the instruction range for the CPU as "normal" instructions may be used to manipulate the internal registers rather than having special purpose instructions dedicated to the manipulating of the registers.

Abstract: ABSTRACT An arithmetic circuit responsive to two sets of input data represented in two's complement form for carrying out consecutive addition or subtraction is described.  In such circuits according to the prior-art various techniques were used to overcome the problem of overflow in the consecutive addition operation, one such technique being to correct the result of the operation every time over-flow occurred.  The invention described represents a significant departure by not compensating for overflow each time it occurs.  Instead, the complete sequence of consecutive addition operations is allowed to proceed with overflows in both directions.  If, ultimately, there are an equal number of positive as negative overflows, no correction is necessary.

The side walls are adjustably supported on the machine frame for adjustment laterally of the machine frame to accommodate top walls of varying widths and the top wall is vertical-ly adjustable relative to the machine frame independently of the side walls.  Power means provide for a controlled relative movement of the side walls, skirt members and top wall and the relative arrangement of the side walls and top wall is such that a glare shield can be formed over any selected section of the barrier wall without interrupting the continuous advance of the machine in the forming of the barrier wall with linear and reversely curved sections.
